Abstract: 606,070. Surface carburetters. MATHESON, G. R. W. Jan. 9, 1946, No. 850. [Class 7 (iii)] The carburetter comprises a casing 1 having air inlets 33, 41, a combustible mixture outlet 31 and a fuel well 19 supplied with fuel from a float chamber 50 by means of a pipe 23. The air supply to the inlet 33 comes from a breather mounted adjacent the engine exhaust pipe and adjustable so that it can be moved towards or away from this pipe. A control valve is employed in the air supply pipe to the inlet 33 and another control valve controls the air inlet 41. Air drawn through these inlets by engine suction applied at 31 passes around the outside of a casing 12 located in the casing 1, past a skirt 12<1> of this casing. From the skirt the air passes over the surface of or into the surface of fuel located in the well 19. The interior of the skirt 12<1> forms a mixing chamber and from this chamber mixture passes up through the inside of the casing 12, which is packed with dehydrating material, preferably of copper clippings, to the outlet 31. A fan 28 is located in the mixing chamber and this may be driven by a variable speed electric motor 29. A perforated plate 18 is located in the fuel well. The supply of mixture from the outlet 31 to the engine is controlled by two interconnected hand-operated throttle valves (not shown). A "back fire valve" may be located on the engine side of the throttle valves. Vanes 17 serve to give the air a swirling motion before it passes over the surface of the fuel.

Filed: 1942-01-23
Abstract: 555,831. Parachutes; balloons. INGRAM, G. Jan. 23, 1942, Nos. 963 and 5451. [Class 4] Parachutes are combined with balloons that are inflated by air or gas, and serve for effecting the opening or controlling the descent of the parachute or for maintaining it suspended for a period prior to descent. According to Fig. 1 the balloon 1 serves both to effect the opening of and to sustain the parachute 2 but instead, there may be a relatively small balloon serving only to effect the opening of the parachute, or two disposed one above the other within the parachute, one for opening and the other for buoyant suspension. The upper part of the balloon may actually form the whole or part of the canopy of the parachute and in one such construction, Fig. 10, the balloon is surrounded by a skirt 12 that provides a degree of parachute support even when the balloon is inflated. In a further construction, Fig. 12, the balloon is disposed above the parachute so that both may function simultaneously. For inflating the balloon, a vessel 19 containing compressed air or gas may be connected directly to the balloon, Fig. 1, the inlet valve being controlled by the suspended person 24 by a cable 22 or the vessel may be attached to the suspended person as in Fig. 13, or the valve may be operated automatically by the tension between the parachute and the load suspended thereby. Deflation may be effected by an escape valve or a rip panel or by both of these devices operable in succession by a single cable. Where the parachute device is used for dropping military supplies, leaflets &c. the balloon can be inflated prior to launching the device and be subsequently punctured by a delay-action fuse device to effect the descent. The balloon may be traversed by a vertical air-duct, controlled at its lower end by a valve, to provide directional control of the descent. Reference has been directed by the Comptroller to Specifications 23081/92, 7712/93, 12907/09, 109,496, 144,046, 275,994 and 302,671, [all in Class 4].
